ELECTRIC I-IEATER.

Be it known that I, Rose SMITH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State 20f Ohio, have invented a new and useful Electric'I-Ieater, of which the follo'wing is a specification.

Th1s1nvent1on relates to improvements in electric heaters, and the primary object ofv whereby an ordinary incandescent or other the invention is the provision of means electric lamp or lamps may be economically utillzed as a source of heat and also as a source of light, the said electric lamp being practically housed in a suitable heat conducting material capable of radiating a large amount of heat, said housing being provided with an adjustable shutter arrangement whereby the light from the lamp may also be Another object of this invention is the pro vision of an electrical heating device adapted to be used in lieu of a hot water bottle, the

same being made in a convenient form or shape and provided with an exteriorly operated means for actuating the light switch and with an exteriorly operated shutter dis- 7 posed in the opposite end from th'elamp to permit the end of the housing to be closedor openedso that the light from the lamp may be utilized.

Withth foregoing and other objects in view. which will appear as the description proceeds, the invention resides in the combination' and arrangement of parts and in I the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1' is a side elevation ofthe complete heater. Fig. 2' is a longitudinal section through the casing or housing showing an electric lamp housed therein. Fig. 3 is an end view of the casing showing the means for utilizing the light of the lamp.

Fig. 4 is a detail View ofthe shutter used in connection with the casing;

designates a cylindrical casing which is preferably made of sheet metal and is formed by stam'pingso that the end 2 thereof, will be formed integral with the walls of the casing, the same being provided with aseg- .mental opening 3, the purpose of whichjwill Specification of Letters fatent. Application filed September 13 ,191 1. Serial No. e49,04a.

Referring tothe drawings, the numeral 1' I 'Patentedif lindrical casing is formed withthreads as at a for the removable reception of the plug or cap 5 formed of insulating material. the

the observer to ascertaiuwh'et her oriiot the filament 1n the lamp is incandescent or burned out. v 1

In the sealed end 2 of the casing is aconcentric pin or pivot 10, whereby the shutter 11 is mounted for rotation within the casing, the said shutter being provided with a'segmental aperture 12, which is adapted to match or aline with or be moved in various adjustable positions with relation to the segmental opening 3 of the casing, said end 2 being further provided with the arcuate .slot or groove 13 for the engagement and movement of the button 14 which'is connected to the shutter 11, whereby the said shutter may be rotated to cause the aperture 13 to be placed in alinement with the aperture 3 of the casing or to cause the body portion of presently appear. The open end ofthiscy .60 said plug having mounted upon the inner said shut-ter to close the aperture 3 of the a may be turned by meansof the button 14 to bring'its aperture 13 into coincidence with the opening 3 of the casing, thus permitting the rays of light to pass through the openin in the casing and the openingof the shutter to illuminate, the peculiar construction of the casing concentrating the rays to be projected so that the heater may be used as a hand lamp. Ihis shutter 11 also provides a means whereby the heat radiated from the walls of the casing may be regu lated at will, allowing certain amount of the heat to escape through the openings of the shutter and the casing when in coincidence,

thus preventing too great a radiation of heat fromthe Walls of the casing, Where a gentle modified heat is desired, the shutter 11, when acting in the nature of a damper may be moved to the open position, and Where all the heat p'ossible fromthe lamp is necessary the shutter is closed and the lamp is completely housed Within the casing and neither heat nor light escapes therefrom except by radiation of the heat through the walls of the casing.

To renew the lamp it is simply necessary to remove the insulated plug carrying the lamp socket, the lamp being unscrewed and a new one replaced in the ordinary manner.

hat is claimed is:

1. An electric heater, comprising a suitable casing having a closed end with a light passage therein and an arcuate slot concentric thereof, a removable cap plug of insulating material mounted in the open end of said casing, a shutter carried by the closed end of the casing and provided with a passage movable into and out of matching relation with the passage of the closed end of the casing, a lamp socket for an incandescent lamp carried upon the inner face of the 11 W- able plug, and a switch operating means it: i

the lamp disposed upon then I I l i l l gerlface 0t said cap plug.

2. An electric heater, comprising a suitable casing having a closed end with a light passage therein and an arcuate slot concentricthereof, a removable cap plug ofinsulating material mounted in. the open end of said casing, a shutter carried by the closed end of the casing and provided With a passage movable into and out of matching relation with the passage of the closed end of the casing, a lamp socket for an incandescent lamp carried upon the inner face of the removable plug, a switch operating means for the lamp disposed upon the outer face of said cap plug, and a button carried by the shutter and disposed through the arcuate slot in the closed end of the casing to permit of the oscillation of the shutter Within the casing.

In testimony that I claim the foregoing my own, I have hereto aiiixed my signature in the presence of two witnesses.
